    摘要： A system and method for messaging in which, when a connection to a queue manager (220) is established, the queue manager allocates a Connection Identifier from the same name space (300) as Message Identifiers and returns this information (400) to the user. The user can then use this Connection Identifier as a Correlation Identifier, safe in the knowledge that it will not clash with any system generated Message Identifier or Correlation Identifier. A secondary benefit to this allocation scheme is that if a shared reply queue suffers from a build-up of messages then the Correlation Identifier in those messages can be used to identify the application expected to receive those messages.

    摘要翻译： 一种用于消息传递的系统和方法，其中当建立与队列管理器（220）的连接时，所述队列管理器从与消息标识符相同的名称空间（300）分配连接标识符，并将该信息（400）返回给用户 。 然后，用户可以使用此连接标识符作为相关标识符，安全的是它不会与任何系统生成的消息标识符或相关标识符冲突。 这种分配方案的次要好处是，如果共享应答队列受到消息的建立的影响，那么这些消息中的相关标识符可用于标识预期接收到这些消息的应用程序。

    摘要： A method and computer program product is provided for sending a persistent message in a transaction-enabled messaging and queuing system. A message queue manager is responsible for transferring messages from a sender program to a receiving program via a message queue. A message is sent from the sender program to the message queue manager. The message is defined to permit the message queue manager to select whether to treat the message transactionally or non-transactionally.

    摘要： The invention relates to controlling access by a plurality of concurrently operating processes to a resource. An area of storage is allocated and a pre-determined number of slots defined therein. Responsive to a request by one of the processes for shared access to the resource, a determination is made as to whether to allocate shared access, and if so, the requesting process is allocated shared access upon the acquisition of one of the storage slots. Responsive to a request by one of the processes for exclusive access to the resource, a determination is made as to whether to allocate exclusive access, and if so exclusive access is allocated upon the acquisition of all of the storage slots.

    摘要： Documents are published in a publish subscribe data processing system. A first document to be published may have an associated topic. The first document is retained as a retained document. A second document to be published is retained as the retained document in response to receiving the second document before a predetermined time interval has passed. A copy of the second document is sent to a subscriber of the topic. A copy of the retained document is sent to the subscriber of the topic in response to a determination that the predetermined time interval has passed.

    摘要： A method and system for combined commit transaction request and subsequent operation request for committing the operations of a synchronized transaction by one or more applications (301, 4001, 501) on a resource manager (302, 402, 502). The method comprises: receiving a combined request (310, 410, 510) for an operation and a request to commit any outstanding synchronized transaction; committing the outstanding transaction (311, 414, 512); and processing (313, 413, 517) the requested operation outside the outstanding transaction. For example, in an asynchronous messaging process, the combined request specifies an option in a get operation request to commit any outstanding units of work prior to carrying out the get operation.

    摘要： A method and system of inherited transactions in an asynchronous messaging are provided. A producer requests a message put operation in a transaction. A consumer carries out a get operation with the option to inherit the transaction of the put operation. In an inherited transaction, the consumer's transaction will not commit until the transaction it has inherited from commits. Work performed in the producer's transaction is visible to the consumer, but work performed in the consumer's transaction is not visible to the producer preserving asynchronous messaging semantics. A transaction hierarchy results and only the net effect of transaction hierarchy is hardened to non-volatile storage.

    摘要： A method for deleting expired items in a queue data structure, the queue data structure comprising a sequential list of ordered data items including a queue head at one end of the sequential list and a queue tail at another end of the sequential list, wherein each data item includes an expiry time, the method comprising: generating a maximum interval value corresponding to a maximum time interval between an expiry time of a first item in the queue and an expiry time of a second item in the queue, wherein the second item is nearer the queue head than the first item; sequentially scanning the list of ordered items from the queue head; responsive to a determination that a scanned item is expired, deleting the scanned item; responsive to a determination that a scanned item will not expire for a time interval greater than the maximum interval value, terminating scanning of the list of ordered items.
